Get all three to add to your workshop.

Your tiny hex wrenches aren’t strong enough to remove your pedals or cranks after a couple days of muddy riding. To take apart your thrashed crankset, you’ll need a Hex Tool built by Park Tool. The strong, steel stem provides the leverage you need, and the ergonomic screwdriver grip allows you to torque loose even the most hopelessly stuck bolts. A ball driver hex on the opposite end lets you turn screws from obscure angles. Pick any one of three Hex Tool sizes to fit the job.

The 6mm Hex Tool has the shortest stem and is suited for pedals

The 8mm Hex Tool features a medium-sized stem and works for pedals and cranks

Required for Crank Brothers Pedals

These are pretty much required tool box items if you run Crank Brothers pedals. True to Crank Brothers form, they put aesthetics over function and don't put pedal wrench flats on the axles of their pedals.

When a pedal seizes, it is a mother to get off with other hex wrenches. Short ones rip a hole through the palm of your hand and long ones just flex. Not these bad boys. They are super stiff; zero flex. And the hand grip is perfect for your palm.

I recently had a pedal seize that I could not get off for the life of me. I had ripped my hands to shreds. I had heated the crank arms with a soldering iron. I had studied white papers on the laws of mechanical leverage. It was not budging...until I picked up one of these. It literally popped off in seconds after weeks of trying.

It is all about the right tool for the job. Get the 6mm for Mallets and the 8mm for Eggbeaters.
